Video stabilization not working? Start here

1. The video looks exactly the same

Compare the original and processed previews at the same point in the clip. Look at stable background edges, such as a wall or horizon, rather than only the moving subject.

• Minor original shake: there may be little to correct.
• Strong motion blur: the camera may have blurred each individual frame; stabilization alone may not fix it.
• Intentional motion: panning or rapid movement can be difficult to distinguish from unwanted shake.
• Unexpected processing behavior: the output might not have been transformed as expected. Treat this as a possible bug, not proof of success.

Try a small clip with obvious unwanted shake and compare it carefully. If the output remains unchanged, use the feedback form on the stabilizer homepage.

2. Processing is taking far too long

Browser processing requires CPU time and memory on your own device. A long, high-resolution or complex file can be significantly slower than a short MP4. If processing seems stuck, do not wait indefinitely without checking the status.

1. Try a short recording rather than an entire long video.
2. Close memory-heavy tabs and ensure your device has available resources.
3. If the page reports a processing error, read it before trying again.
4. Use the Fast quality option as a diagnostic starting point if that option is available for your clip.
5. If you reproduce an unusually long or frozen run, report the approximate clip length, format and device type—never upload private footage unless you choose to share it by another channel.

We are investigating reports of extremely long processing and insufficient visible improvement. Until verified fixes are released, avoid promises of a specific completion time.

3. The video cannot be opened

A file extension alone does not indicate the underlying video codec. A .mov or .mp4 recording might contain HEVC/H.265 or other codecs with different browser and memory requirements. Very large files can also fail during local processing.

Try a smaller recording or a broadly compatible H.264 MP4 clip if you have one. The tool has compatibility handling for some HEVC inputs, but not every file can be guaranteed to work on every device.

4. Playback and download checks

After processing finishes, verify the generated preview is playable, compare it to the original, and confirm the downloaded file plays in your device's video player. If playback fails, note the file format, browser and any visible error message. A completed progress indicator is not by itself proof that the output is good.

5. Send useful feedback

The homepage feedback form lets you rate your experience and describe the problem. Helpful details include browser, device, approximate video duration and whether the clip is unchanged, too slow or unplayable. You can leave the optional email field blank. Please do not enter passwords or private video content in your comment.
